In a multicenter prospective randomized double-blind placebo-controlled trial, the investigators would like to compare the analgesic effect and safety of the intravenous morphine 0.10 mg/kg and midazolam 0.04 mg/kg with the intravenous morphine 0.10 mg/kg and placebo in pre-hospital traumatic adults. Assessment will be done at the baseline using a validated numeric rating scale (NRS).
